Cox 049 fuel tank modification

Modification of the fuel tank on a Cox Baby Bee engine to achieve long run times. Uses the original fuel tank as an engine mount, but changes the fuel line to tie into a larger fuel tank. This allowed the small Cox 049 engine to be used to launch radio control gliders; providing 10-15 minutes of run time to gain altitude. This eliminated the need to use a tow plane or hi-start system to launch the glider. Excellent choice for the vintage Craft-Air Butterfly power trainer with 99-inch wing span.
